ADJUSTMENTS & OPERATION
ADJUSTING THE BLADE TENSION
To tighten the blade, turn the blade tensioning knob (A) Fig.14 clockwise. There is a
tension scale guide on the block (B) that shows how tight the blade should be,
depending on the blade width. A rule of thumb, the blade should deflect 1” when
pushed with moderate pressure at the midpoint of the wheels.
TRACKING THE BLADE
WARNING:
Never track the blade when the machine is running. Manually turn the
wheels.
After tension has been applied to the blade, spin the upper wheel forward by hand
and watch the blade. The goal is to have the blade travel in the center of the upper
tire. If the blade creeps toward the front of the wheel, turn the tracking knob (C)
Fig.14 clockwise, drawing the blade toward the center. This adjustment is very
sensitive, so only turn the knob a small amount at a time. If the blade creeps towards
the back, turn the tracking knob counterclockwise. Once you are confident that the
blade is tensioned and tracking properly, reinstall the upper and lower blade guard
covers.
ADJUSTING BLADE GUIDE BLOCKS AND BEARINGS
Adjust the blade guides and bearings only after the blade has been tensioned and is
tracking properly.
1.
Upper blade guides:
The upper blade guide blocks (A) Fig.15 are held in place
by butterfly screws (B). The blocks should be very close to each side of the blade
but not too much as to pinch it. Adjust then retighten the butterfly screws. The
blocks should sit back far enough so that the teeth of the blade are out in front of
the blocks, as shown in illustration in Fig.15. To make this adjustment, loosen
butterfly screw (C) and turn the adjustment nut (D). The bracket which holds the
blocks will move back or forth, retighten butterfly screw (C). The back-up bearing
(behind the blade guard) should be adjusted so that it sits 1/16” (approx.) from the
back of the blade. Its purpose is to prevent the blade from being pushed back too
far into the guide blocks. To adjust, loosen butterfly screw (behind the blade guard)
and turn the adjustment nut (E). The bracket which holds the back-up bearing will
move back or forth, retighten butterfly screw.
2.
Lower blade guides:
The lower blade guide blocks and back-up bearing are
adjusted in the same manner as the upper blade guide blocks, but instead of
loosening a hex. bolt on the side, the two hex. bolts on the top of the bracket (A)
Fig.16 are loosened to move the guide blocks back and forth. Again, the blocks (B)
should be very close to each side of the blade but not too much as to pinch it.
Adjust then tighten the butterfly screws (C). The bearing (D) should sit
approximately 1/16” from the back of the blade. It is adjusted by loosening the
butterfly screw (E) on the side of the blade guide assembly. Adjust and retighten.
OPERATION
WARNING:
Do not plug the saw into a power outlet or try to operate until the saw is completely assembled, wired, belt is aligned and tensioned
and the blade is tensioned and tracking properly.
UPPER BLADE GUIDE ASSEMBLY
Before operating the saw, always adjust the blade guard so it just clears the top of the workpiece. Not only is it safer, but it will hold the blade in
position for more accurate cuts. To adjust, loosen the lock knob which holds the guide post, slide the guide post and assembly into position and
retighten lock knob.
TILTING THE TABLE
The table can be tilted to make mitered and angled cuts. To tilt the table, loosen the two lock knobs on the underside of the table and trunnion,
tilt the table to the desired angle using the table angle scale as a guide and retighten the two lock knobs.
